17 Signs of Problems with Ball Mills: Quickly Remove
Oct 28, 2021Find the abnormal signs early is very important to prolong the ball mill service life. 1. The sign of "swollen belly" Just like a bloated stomach, if the amount of grinding exceeds the maximum capacity and discharge capacity, it will cause the mill shell to loses its grinding capacity, and that's why we call it "swollen belly".

Feb 13, 2017The peripheral discharge type of Ball-Rod Mill is a modification of the grate type, and is recommended where a free gravity discharge is desired. It is particularly applicable when production of too many fine particles is detrimental and a quick pass through the mill is desired, and for dry grinding.

Peripheral Discharge Ball Mills -Theory and Practice
Mar 14, 2016When a ball-mill fitted with a diaphragm is over-fed, the mill fills up to a certain level, then stops crushing and discharges any additional feed back through the feed trunnion. Once over-fed, it takes from 30 min. to 2 hr. to free itself.

Converting a ball mill from overflow to grate discharge
Jun 23, 2020In some operations, grate discharge mills can lead to unscheduled downtime due to grate failure, blockage of grates due to sticky ores or poor design, and increased ball consumption due to high wear rates of grate apertures causing loss of media from the mill. In addition, not all mills are suitable for conversion.

Ball mill Wikipedia
Industrial ball mills can operate continuously, fed at one end and discharged at the other end. Large to medium-sized ball mills are mechanically rotated on their axis, but small ones normally consist of a cylindrical capped container that sits on two drive shafts ( pulleys and belts are used to transmit rotary motion).

Mill should not be overcharged or undercharged Overloading tends to accumulate fines at the toe of the mill which results in a cushioning effect. When the rock load is low, excessive ball-to-ball contact retards the rate of breakage. The fraction of mill volume occupied by the ore, J↓R: J↓R=M↓R / Ï â†“S / V↓M x1 / 1—φ M R = rock mass

The Reason of Ball Mill’s Uneven Discharging PHDessay
May 29, 2017Grinding the material evenly or not seriously affects the production efficiency of ball mill. Uneven ball mill’s discharging may be caused by the following two aspects: Firstly, the feeding grinding materials cause the uneven discharging. When water into the grinding material is high, it may cause the ball mill grinding "full" phenomenon.

Converting a ball mill from overflow to grate discharge
Jun 23, 2020If a mill has available power, conversion of the discharge arrangement from overflow to grate can be beneficial in allowing increased throughput or a finer product size. Conversely, if the mill does not have available power then it is still possible to install a grate discharge and to draw the same power by using a lower ball charge.
